Intense mid-infrared excitation has been demonstrated as a powerful tool for controlling the magnetic, ferroelectric and superconducting properties of complex materials. Nonlinear phononics is key to this end, as it displaces ...
Over the last 35 years, scientists have investigated a special type of materials called superconductors. When cooled to the correct temperatures, these materials allow electricity to flow without resistance. One team is ...
Scientists from the Fritz Haber Institute of the Max Planck Society, Vanderbilt University, City University of New York, University of Nebraska, and University of Iowa have just published new results on asymmetric light-matter ...
Atomically thin two-dimensional (2D) materials can provide highly interesting excitonic properties, which render them an attractive platform to explore polaritonic physics.
Recently, the Kagome superconductors AV3Sb5 (A = K, Rb and Cs) have attracted enormous attention due to their novel phenomena and rich physics. They exhibit unconventional charge density wave (CDW), giant anomalous Hall effect ...
Phonons are collective atomic vibrations, or quasiparticles, that act as the main heat carriers in a crystal lattice. Under certain circumstances, their properties can be modified by electric fields or light. But until now, ...
In a closed physical system, the sum of all angular momentum remains constant, according to an important physical law of conservation. Angular momentum does not necessarily need to involve "real" bodily rotation in this context: ...
A study published in Advanced Materials reveals the thermal transport properties of ultrathin crystals of molybdenum diselenide, a two-dimensional material of the transition metal dichalcogenide (TMD) family. Outperforming ...
Researchers have known about high-temperature superconducting copper-based materials, or cuprates, since the 1980s. Below a certain temperature (approximately -130 degree Celsius), electrical resistance vanishes from these ...
Vanderbilt researchers Sokrates Pantelides and Joshua Caldwell are part of an international collaboration that has demonstrated a new way to manipulate and measure subtle atomic vibrations in nanomaterials. This breakthrough ...
